HOW TO FIX "413 Payload too large" in NodeJS (Express)

413-payload-too-large-fix.js

const express = require('express');
const bodyParser = require('body-parser');

...

// Express 4.0
app.use(bodyParser.json({ limit: '10mb' }));
app.use(bodyParser.urlencoded({ extended: true, limit: '10mb' }));

// Express 3.0
app.use(express.json({ limit: '10mb' }));
app.use(express.urlencoded({ limit: '10mb' }));

...

⚠️It was bun runtime for me. Replaced bun runtime with node and it works. Could not find any settings for bun regarding this.⚠️

🔴 This was all bun runtime's fault from now on

Well, nothing works for me.
I always got 413 response.
I'm using BUN as runtime, express v4.21.2 and body-parser v1.20.3

Try 1

import express from "express";
import { json, urlencoded } from "body-parser";
// import { json, urlencoded } from "express"; // I have tried this as well

const payloadLimit = 2000 * 1024 * 1024; // 2000 MB in bytes
const appOptions = {
  extended: true,
  limit: payloadLimit,
  parameterLimit: payloadLimit,
};

app.use(express.json());
app.use(json({ ...appOptions }));
app.use(urlencoded({ ...appOptions }));

Try 2

import express from "express";
import { json, urlencoded } from "body-parser";
// import { json, urlencoded } from "express"; // I have tried this as well

const payloadLimit = 2000 * 1024 * 1024; // 2000 MB in bytes
const appOptions = {
  extended: true,
  limit: payloadLimit,
  parameterLimit: payloadLimit,
};

app.use(json({ ...appOptions }));
app.use(urlencoded({ ...appOptions }));
app.use(express.json());

Try 3

import express from "express";
import { json, urlencoded } from "body-parser";
// import { json, urlencoded } from "express"; // I have tried this as well

const payloadLimit = 2000 * 1024 * 1024; // 2000 MB in bytes
const appOptions = {
  extended: true,
  limit: payloadLimit,
  parameterLimit: payloadLimit,
};

app.use(json({ ...appOptions }));
app.use(urlencoded({ ...appOptions }));
app.use(express.json());

Try 4

import express from "express";
// import { json, urlencoded } from "body-parser";  // I have tried this as well
import { json, urlencoded } from "express";

const payloadLimit = 2000 * 1024 * 1024; // 2000 MB in bytes
const appOptions = {
  extended: true,
  limit: payloadLimit,
  parameterLimit: payloadLimit,
};

app.use(json({ ...appOptions }));
app.use(urlencoded({ ...appOptions }));
app.use(express.json());

Try 5

import express from "express";
// import { json, urlencoded } from "body-parser";  // I have tried this as well
import { json, urlencoded } from "express";

const payloadLimit = 2000 * 1024 * 1024; // 2000 MB in bytes
const appOptions = {
  extended: true,
  limit: payloadLimit,
  parameterLimit: payloadLimit,
};

app.use(express.json());
app.use(json({ ...appOptions }));
app.use(urlencoded({ ...appOptions }));

It's just don't want to work. It works on localhost but not on server.
The proxy maintainer said that it is my app's fault.
